Overview
This OEM condenser fan motor (part number 1177713) drives the outdoor fan blade on your Tempstar T4H424GKD100 heat pump. Rated at 1/12 HP, it pulls air across the outdoor coil to reject heat in cooling mode and absorb heat in heating mode — without it, the system loses its ability to exchange heat and head pressure climbs until the compressor trips on overload. The motor's bearings, windings, and capacitor circuit all wear over years of continuous outdoor service in heat, cold, rain, and dust. A failing fan motor is a leading cause of a condenser that runs hot, trips the breaker, or cuts out on a high-pressure or thermal-overload fault. Replacing it promptly protects the far more expensive compressor from running against poor heat rejection.

Compatibility
Factory-specified for the Tempstar T4H424GKD100 heat pump and used across matching ICP-family condensing units (Heil, Comfortmaker, Arcoaire). Before ordering, confirm the horsepower, rotation direction, shaft diameter, mounting, and run-capacitor microfarad rating match your existing motor.
Installation Guide
- Safety First — Disconnect power at the disconnect and breaker, then verify zero voltage with a multimeter; the run capacitor can hold a charge — discharge it safely.
- Access — Remove the top fan grille/shroud and lift the fan assembly clear of the cabinet.
- Document — Photograph the wiring, capacitor leads, and the blade's position and orientation on the shaft.
- Remove — Loosen the blade set screw, pull the blade, then unbolt the old motor from the bracket and free the leads.
- Install — Bolt in the new motor, transfer the blade to the same shaft depth and orientation, and wire to the capacitor and contactor per your photo.
- Test — Restore power, call for cooling, and verify the fan spins the correct direction at full speed with no wobble.
Signs You Need a Replacement
- Outdoor fan won't start, hums, or needs a push to spin.
- Loud grinding, squealing, or rattling bearings.
- Condenser runs hot and trips on high-pressure or thermal overload.
- Motor cuts out intermittently as it heats up.
